8 Track Bluetooth Adapter

Looked for a way to keep my classic car 100% stock but still get bluetooth in it somehow, then i thought of this! Once you realize there is 12 volts readily available in any 8 track player the world opens up to you haha (12v is pulled from the track changing sensor in the player). Simple concept. Take the 12 volts in the 8 track player, reduce it to 5 volts using a gutted car usb charger, and then power a bluetooth module (and LED to show that its powered on). that simple! just hot glued it all in place as seen in the diagram.

Also, the USB has an extra unused port SO YOU CAN CHARGE YOUR PHONE TOO!!!

Honestly sounds better than any of my 8 tracks lol

Step by step wiring instructions:

After you have everything in front of you, take the shell off the USB charger. Desolder one of the USB ports to get access to the solder pads. Solder 2 + wires to the + side of the USB pads, and 2 to the - pads. These will be your 5V power supplies for the LED and bluetooth module. Put a 330 o
